2. INTRODUCTION
3. PRODUCT DESCRIPTION
The SBT system consists of a number of parts of which the
Plymovent yellow and black extraction hose assembly is most
visible to the user.
The extraction hose has a Safety Disconnect Coupling built
in, this to protect the system against misuse. The hose is
positioned in the Saddle which connects to the balancer. The
balancer is connected to the aluminium track via a special
trolley. This enables the balancer to move inside the aluminium
profile which is positioned above and to the tailpipe side of the
vehicle.
The aluminium profile is designed to a three (3) section
principle of which two (2) sections have open areas, one on
the underside and one on the overside. The overside open area
is used for positioning the support legs, duct and exhaust hose
connector and the release valve. The underside open area is
used for positioning the end stops and for the sliding the
trolley.
Method of use:
An automatic, pneumatic controlled exhaust gas extraction
system, specially designed for fire and rescue vehicles with low
level, side exhaust pipes. The system is used to remove the
poisonous petrol and diesel gas fumes direct at the emission
source, the exhaust pipe.
When the vehicles are on their way out of the station, the
extraction hose, connected to the exhaust by a special device
called a Grabber®, moves along with the vehicle.
Poisonous diesel gases pass from the Grabber®, up the
extraction hose and into the ducting and extraction fan before
escaping to the atmosphere.
As the vehicles drive out through the doors, the trolley moves
over a release valve on the track, which releases the air
pressure in the Grabber® allowing it to disconnect the ex-
haust pipe.
On the return of the vehicle to the station, The SBT
Pneumatic Grabber
®
is easily re-connected to the exhaust
pipe. At the same time the fan automatically starts up and the
vehicle continues to its standard park position.
WARNING!
The use of exhaust removal hose is allowed for:
- Moving of diesel-vehicles in- or out halls / stations.
- Short time maintenance work of diesel-vehicles,
but only if the engine is running on the minimum
rpm.
- The vehicle must leave and enter the station with
a modified speed in order to avoid damage to the
system and possible injury to people.
